Any soap works about as well as povidone iodine (Betadine�), so there is
no real reason to dig into the medic's stocks of that. The lesion should be
covered with a Band- Aid� or similar simple dressing when possible; this prevents lesion-to-nose colonization. Similarly, if the patient has any insect bites, poison ivy or other sites that are
prone to scratching, covering them with a minimal dressing can prevent
infection spread.
